The University of Calgary's Rothney Astrophysical Observatory (RAO) is much more than a spot on a picturesque hill in the Foothills of the Rockies - it is a place where Teaching and Research connects with Public Education and Community Engagement. Where else can school children, teachers, community groups, and anyone else with a curiosity for STEM become immersed in an astronomical research facility and engage with astrophysicists-in-training and seasoned scientists? This is our mission, and it happens both under the stars and under the Sun.
The Rothney Astrophysical Observatory Team Astro virtual programs are ready to Go!
We are currently not offering in person programming until 2022. We will be opening in stages according to direction from the University of Calgary. We miss seeing all of you under the stars. Please watch our website for details and updates.
It's our 50th anniversary year
The Rothney Astrophysical Observatory officially opened on January 7, 1972, beginning a journey of research, science education, and dark skies advocacy in southern Alberta.
